Radiation imaging apparatus
Provided is a radiation imaging apparatus including: a sensor; and a casing enclosing the sensor. The casing includes a front cover, a rear cover arranged at a position opposed to the front cover, and a frame arranged between the front cover and the rear cover. The frame is formed of a plurality of members including two frame members which are mountable to and removable from each other.
1. A radiation imaging apparatus comprising:
a sensor configured to detect a radiation and convert the radiation into an electrical signal related to a radiation image; and
a casing enclosing the sensor,
wherein the casing includes a front cover having an incident surface which the radiation enters, a rear cover arranged at a position opposed to the front cover, and a frame arranged between the front cover and the rear cover,
wherein the frame is formed of a plurality of members including a front frame member and a rear frame member which are mountable to and removable from each other, and
wherein at least one of the front cover or the rear cover is made of a material having a specific gravity smaller than a specific gravity of the frame.
2. The radiation imaging apparatus according to claim 1 , wherein the rear frame member is to be coupled to the front frame member.
3. The radiation imaging apparatus according to claim 1 , wherein the front frame member and the rear frame member are coupled and integrated with each other through intermediation of a fixing member.
4. The radiation imaging apparatus according to claim 1 , wherein the front frame member and the rear frame member are separated away from each other so that the sensor is allowed to be taken in and out of the casing.
5. The radiation imaging apparatus according to claim 1 , wherein at least one of the front frame member and the rear frame member is made of a metal.
6. The radiation imaging apparatus according to claim 1 , wherein the front frame member and the rear frame member are electrically connected to each other through contact.
7. The radiation imaging apparatus according to claim 1 , wherein the frame partially includes an extending portion projecting to an inner side of the rear cover when viewed from a rear cover side.
8. The radiation imaging apparatus according to claim 7 , further comprising an electric board between the extending portion and the sensor.
9. The radiation imaging apparatus according to claim 1 ,
wherein the casing has an opening formed at a position opposed to the front cover, and
wherein the radiation imaging apparatus further comprises, between the opening and the sensor, at least one electric component among a wireless communication unit, a wireless electric supply unit, and a speaker.
10. The radiation imaging apparatus according to claim 1 , wherein the front cover is made of a resin.
11. The radiation imaging apparatus according to claim 1 , wherein at least one of the front cover or the rear cover is made of a carbon fiber reinforced resin.
12. The radiation imaging apparatus according to claim 1 , wherein the front cover is bonded to the front frame member with an adhesive material, and the rear cover is bonded to the rear frame member with an adhesive material.
13. The radiation imaging apparatus according to claim 1 , wherein the rear cover has a recess portion recessed in a direction inward of the casing, and
wherein the recess portion has a depth of ½ or more of a thickness of the radiation imaging apparatus in a direction in which the radiation enters the radiation imaging apparatus.
14. A radiation imaging apparatus comprising:
a sensor configured to detect a radiation and convert the radiation into an electrical signal related to a radiation image; and
a casing enclosing the sensor,
wherein the casing includes a front cover having an incident surface which the radiation enters, a rear cover arranged at a position opposed to the front cover, and a frame arranged between the front cover and the rear cover,
wherein the frame is formed of a plurality of members including a front frame member and a rear frame member which are mountable to and removable from each other, and
wherein at least one of the front cover or the rear cover includes a conductive part and a non-conductive part, and
wherein the conductive part is electrically connected to the frame.
